False. When matter changes state/phase, it still has the same molecular formula. It would be a physical change.

What is her displacement
Aleks04 [339]

Answer:

c) 2 blocks

Explanation:

Her displacement is the difference between her starting point and her ending point.

Let's say she starts at the origin, (0, 0).

First, she goes 13 blocks east: (13, 0)

Next, she goes 4 blocks north: (13, 4)

Then she goes 8 blocks west: (5, 4)

Then she goes 6 blocks south: (5, -2)

Finally, she goes 5 blocks west: (0, -2)

The magnitude of her displacement is the distance between her initial and final positions: 2 blocks.

A positively charged object is brought near but not in contact with the top of an uncharged gold leaf electroscope. The experime
Olin [163]

Answer:

The leaves of the electroscope move further apart.

Explanation:

This is what happens; when the positive object is brought near the top, negative charges migrating from the gold leaves to the top. This is because the negative charges in the gold are attracted by the positive charge. Thus, it leaves behind a net positive charge on the leaves, though the scope remains neutral overall. To that effect, the leaves repel each other and move apart. If a finger touches the top of the electroscope at the moment when the positive object remains near the top, it basically grounds the electroscope and thus the net positive charge in the leaves flows to the ground through the finger. However, the positive object continues to "hold" negative charges in place at the top. Ar this moment the gold leaves have lost their net positive charge, so they no longer repel, and they move closer together. If the positive object is moved away, the negative charges at the top are no longer attracted to the top, and they redistribute themselves throughout the electroscope, moving into the leaves and charging them negatively.

Thus, the leaves move apart from each other again and we now have a negatively charged electroscope. If a negatively charged object is now brought close to the top, but without touching, the negative charges already in the electroscope will be repelled down toward the leaves, thereby making them more negative, causing them to repel more, and hence move even further apart.

So, the leaves move further apart.

Explanation:

Practical example below

Distance of door handle is 5m. Force is 5N

Moment = Force × distance

=5×5

=25Nm

Distance of door handle is 7m. Force is 5N

= 7×5

=35Nm

Therefore proven correct
